Double-Stranded RNA in Strawberry Plants Infected with Strawberry Mild Yellow-Edge Virus. Sara Spiegel, Virus Laboratory, Agricultural Research Organization, The Volcani Center, Bet Dagan 50-250, Israel; Phytopathology 77:1492-1494. Accepted for publication 1 May 1987. Copyright 1987 The American Phytopathological Society. DOI: 10.1094/Phyto-77-1492.

Double-stranded RNA (dsRNA) has been isolated from strawberry plants infected with strawberry mild yellow-edge virus but not from virus-tested plants. Three major dsRNA bands were present in 20 independent extractions from two cultivars. These bands had relative molecular masses of 3.8, 2.8, and 1.3 106 Da. These dsRNA species are similar to those previously reported for dsRNA from plants infected with the well-characterized luteoviruses barley yellow dwarf virus and beet western yellows virus.
